Derek, who carries the message across the channel, is like a neurotransmitter because he is the messenger who transports the message from one side (axon terminal) to the other side (dendrites) of the "synaptic cleft" (river). Just like a neurotransmitter carries signals between neurons, Derek carries the message between two individuals separated by a physical barrier.
